It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |

I think that the existing tests should cover this change well enough. It might be possible to create a test that checks that the scrolling performance is still good for when the list has a lot of packages, but experience leads me to believe that such a test could be potentially flaky, and probably more effort to implement than it's worth. |

I think you have to ping someone for this to be test exempt. I've seen it in a couple PR. |

Yes, I was hoping to figure out how to get a reviewer assigned first 😅
I'll ping hixie on discord later

Overall this looks good with just one tiny fix.

For apps with a large amount of dependencies, LicensesPage can become slow on some older devices. Using ListView.builder() instead of ListView() reduces the likelihood of that.
